Abstract: Heat transfer model on the thermal control groupware of thrust chamber for orbit 5N propellant hydrazine thruster is established. Thermal analysis and numerical computing with finite element method are fully performed. Then computed results are validated in heat vacuum test. As a result, significant references and useful guidance are supplied for further developing and manufacturing attitude control thrusters which have new construction and performance as well as the other similar thrusters.
